Our precious metal spring contacts are available in fine patterns, which contributes to product miniaturization.

Multi-wire brush contacts have a multi-point contact structure which consists of fine wires in parallel bunches and provides high contact reliability. Multi-wire brush contacts can reliably read electrical signals from fine patterned circuits, thereby miniaturizing the product size.
Scratch brush contacts, in combination with clad materials (see Precious Metal Clad Materials), use high-performance precious metal contact materials only in limited areas. There are various contact materials available with a high cost performance to suit various applications.
Various types of brush contacts are available in multiple contact shapes, from cost-effective standard products to advanced customized products.
